Abstract

Method and apparatus for determining a metric for use in predicting properties of an unknown specimen belonging to a group of reference specimen electrical devices comprises application of a network analyzer for collecting impedance spectra for the reference specimens and determining centroids and thresholds for the group of reference specimens so that an unknown specimen may be confidently classified as a member of the reference group using the metric. If a trait is stored with the reference group of electrical device specimens, then, the trait may be predictably associated with the unknown specimen along with any traits identified with the unknown specimen associated with the reference group.

Description

[0001] This application is a continuation-in-part of U.S. patent application Ser. No. 12 / 823,303 filed Jun. 25, 2010 and claims priority to provisional U.S. Application Ser. No. 61 / 485,206 filed May 12, 2011, the entire disclosures of which are hereby incorporated by reference into the present application.

[0002] This invention was made with U.S. Government support under contract W9113-09-C-0188 awarded by U.S. Army Space and Missile Defense Command / U.S. Army Forces Strategic Command. The U.S. Government has certain rights in the invention.TECHNICAL FIELD

[0003] The technical field relates to a method and apparatus for classifying specimens and media using spectral properties and identifying unknown specimens and media having like spectral properties and, in particular, to the application of a spectral property database having one or more data values representative of spectral properties such as magnitude, phase or complex values sampled at discrete values of time, frequency, wavelength,...
